Remote Writer not collaborating correctly

I havent changed anything on our side but when I came in today when I open a document in collabedit mode it doesnt show the Collaborating..ready. And, then when i open up with another person to collaborate it shows im in there but the document is not updating on each others docs.

I typed "Hey there"
on the other doc it showed "Hey the"

then it wouldnt show anything

Also, the colored lines indicating who is using that line on the document is not there.
